Tiras was, according to Genesis 10 and Chronicles 1, the last-named son of Japheth who is otherwise unmentioned in the Hebrew Bible. According to the Book of Jubilees, the inheritance of Tiras consisted of four large islands in the ocean. Some scholars have speculated his descendants to have been among the components of the Sea Peoples known to Ancient Egypt as Tursha and to the Greeks as Tyrsenoi. According to tractate Yoma, in the Talmud, Tiras is the ancestor of Persia.
